Mahi-mahi fishing from Sebastian Inlet works the Gulf Stream’s western edge, which the inlet gives access to. Local reporting has dolphin moving north near the Stream, and the charters named here run out through the inlet. This page covers the season, the water, the inlet, the methods and the rules. The Sebastian Inlet port page has the park and ramp details. For the wider coast, see the mahi-mahi fishing in the Atlantic Southeast and the wider Atlantic Southeast guide.
When mahi are around Sebastian Inlet
No mahi month is confirmed for Sebastian Inlet. Local reporting has dolphin moving north near the Gulf Stream in the spring. That fits the regional pattern on Florida’s east coast, where the fish follow the Stream north in spring and push back south in fall as the water cools.
Where boats run
The Gulf Stream’s western edge is reachable from the inlet. Eight Indian River County offshore artificial reefs lie 11 to 12 miles east of the inlet in 65 to 70 feet of water. Sebastian Inlet is a jettied, dredged cut linking the Indian River Lagoon to the Atlantic. Tidal currents in it are reported to reach about 10 knots. Breaking and confused seas are reported off the mouth and inside as far as the bridge except in flat calm, and conditions worsen with rising seas or wind and on the ebb. A return timed for the flood or slack is easier than one on a strong ebb. The A1A bridge has 37 feet of clearance. Shoaling builds just north of the south jetty and gradually shifts, so favor mid-channel. Check the inlet’s webcam and current predictions before you leave, and check conditions yourself.
Grounds and structure
The one named structure confirmed for Sebastian Inlet is the group of eight Indian River County offshore artificial reefs, 11 to 12 miles east of the inlet in 65 to 70 feet. Nothing confirmed ties mahi to them, and no mahi ground is confirmed for the port. The jetties and the shoals inside the inlet are the nearest structure, but they are hazards rather than targets.
How mahi are fished out of Sebastian Inlet
No local method is confirmed for mahi, so the general approach applies. Troll rigged ballyhoo and skirted lures along the edge and the weed at a steady pace, with a teaser in the spread. When a school holds behind the boat, pitch baits into it, keep one hooked fish in the water, and drop the baits back for the followers.
Who fishes it
Big Easy Fishing Charters and Zookeeper Charters are named for the port, both working from the inlet. Neither has a website confirmed here, so contact them directly before you book. Other operators work the inlet, but their mahi listings are not confirmed on this page. No mahi tournament is confirmed.
